Frequently asked questions
Can I view recent transactions across the company?
Yes! Use the list_transactions tool to retrieve recent corporate card usage and merchant details.
How do I check my available budget?
Simply ask the agent to list_budgets to retrieve budget limits and current spend amounts.
Does the integration allow me to create virtual cards?
Currently, the toolset focuses on querying and auditing (listing cards, budgets, transactions). Creating cards must be done on the platform.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your BILL Spend & Expense MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
